British Standard BS25999
BS 25999 has been developed by practitioners throughout the business continuity community, drawing upon their academic, technical and practical experiences of BCM. It has been produced to provide a system based on good practice for BCM.
There are two parts to the BS 25999. The first, "BS 25999-1:2006 Business Continuity Management. Code of Practice", takes the form of general guidelines and seeks to establish processes, principles and terminology for Business Continuity Management. The second, "BS 25999-2:2007 Specification for Business Continuity Management", specifies requirements for implementing, operating and improving a documented Business Continuity Management System (BCMS), describing only requirements that can be objectively and independently audited.

This methodology relates to the Business Continuity Management System (BCMS) as below:
| Plan | Establishing the policy, objectives and scope of the programme |
| Do | Implementing the BCM programme |
| Check | Internal audit and management review of the BCMS |
| Act | Implementing results of the review |
